Application filed January 26, 1916. I Serial No. 74,339,

It is well known to those skilled in the art that it is very often necessary to change the shape of a stiff or Derby hat. This is some times accomplished by stretching the hat with a hat'block, but the only successful way of changing the contour is by first softening the shellac or other stiffening material in the brim of thehat by the application of heat.

The general object of my invention has been to provide a set board which is heated by electricity and upon which the hat may be placed and the stiffening in the brim thereof easily and quickly heated and softened. V

Another object has been to provide a de-, vice of this character which shall be extremely simple, cheap to manufacture, and, at the same time, easy to operate and absolutely fire proof. v 'l The above objects and advantages have been accomplished by the device shown in the accompanying drawings, in which:

Figure 1 is a transverse, sectional elevation taken online 11 of Fig. 2.

Fig. 2 is a fragmentary, sectional, planview of the same with the top part of the insulation broken away, showing the resistance wire exposed. I V

Fig. 3 is a reduced side elevation of my device.

My device comprises-a base 5, which may be of any suitable shape, but it is preferably formed with an upwardly extending side wall 6, and a lower beaded edge 7 to give it sufficient rigidity. The base member 5 is preferably elliptical in its contour.

The-walls are preferably provided with a plurality of apertures 8, whereby suitable ventilation is had so that the heat within 7 the walls may be'carried off.

On top of the base member 5 is disposed a thick pad 9 of refractory material, preferably asbestos. Embedded in this block and near its upper surface is the heating member 10 of my device. This member comprises a resistancewire made of platinum,

German silver, iron or any other suitable material andof a size adapted to the elec trio current used. In practice, fl'form the block 9 ofa thick sheet of asbestos, then ,ITED sTATns PAT OF CE place the resistance wire, forming the mem-'- ber 10, thereon and secure it to the block by any suitable means. I then place on top of the heating member two or three thin sheets of asbestos. V

The resistance wire of the heating member 10 is arranged in a flat spiral and has its inner end startlng at some distance from.

the center of the device, thus leaving a clear elliptical space at the center where heat is not needed. The spiral starts at a point where it will be beneath the brim of the hat and is coiled around in any desired f 1 number of turns until it reaches a point near the outer edge. The terminals of'this heating member are attached to suitable leads 15' which are extended 'down through.

the asbestos block 'Qandare attached to a.

suitable electric connector 11. This connector is of any desired type, but preferably one which can be attached to a source of electric power by means of a flexible electric cord. 7 7

On top of the pad 9 is arranged a-plate .12, upon which the hat is placed. This plate is made of thin sheet metal, preferably of copper, although any other suitable material may be used, if desired. Beneath the block 9' is arranged a sheet of thin material 13, which protects the blockfrom injury." The whole is bound together by means of a plurality of bolts 14, which pass through the upper plate 12, the asbestos vblock 9 and also plate 13, thereby securing these parts 7 12. The hat is now placed upon this plate and. heated until the shellac in the brim is softened, whereupon it may be shaped as desired.

Having thus described my invention, what I claim 1s:

A set board for bats comprising a'base,-

a bottom sheet of thin material locatedon J the base, a thick pad of refractory material mounted on the sheet, a .heatingmember, embedded in the pad, comprising a resist ance wire arranged in a flat spiral, leaving a central space and coiled around" any Tn testiincny wherecfgl have hereunto desired number of turns, an electrical'consigned'my name in the presence of two subnectlon, leads extenchngfromithemcrmeeton SOI'IbIIIgfWItHQSSBSZ;
